Inventor Charles W. Green His Attorney Patented Apr. 5, 1938 UNITED STATES PATENT OFFICE CASH REGISTER Original application September 19, 1931, Serial No. 563,757. gust 27, 1936, Serial 3 Claims.

This invention relates to cash registers and more particularly to machines adapted to print records for auditing purposes of various kinds of transactions, such as cash, paid ou and no sale, and is a division of applicants application Serial No. 563,757, filed September 19, 1931, which issued January 4, 1938 as Patent No. 2,104,588.

The present invention embodies improvements upon the machine disclosed by applicants application Serial No. 13,470 filed March 6, 1925, and issued as Patent No. 1,873,760 on August 23, 1932. Like the machine of the prior application, the present machine is of the key operated type, wherein the operation of selected amount keys simultaneously advances the totalizer and one or more special counters referred to above. The prior application also discloses an arrangement I for printing a running or subtotal, and for print- 20' ing a grand total, by a store manager and an auditor, respectively.

An object of this invention is to provide a novel resetting means for the transaction counters associatecl with the check printer and detail strip printer respectively. Inasmuch as these counters have corresponding numbers, it is desirable that they be reset by the same operation. A difficulty arises, however, in resetting two counters in difierent parts of the machine, because of the friction necessary to be overcome by the reset lever. If the two counters were reset at exactly the same time, the friction would be greatest near the end of the resetting stroke when'all of the totalizer elements are being moved from 9 to As a result, the manager might move the reset lever until the counter elements have all reached the 9 position, and, on finding opposition to the further movement of the lever, fail to complete the resetting operation in the belief that 40 the lever has moved a full stroke. To prevent this, an arrangement is provided for distributing the force necessary to reset the two counters. Accordingly, the counters are so connected with each other and with the reset lever that upon the upstroke of the lever, the check printer counter is restored to zero, while on the downstroke, the counter for the detail strip printer is restored.

With this and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in the appended claims and a preferred form or embodiment of which will now be described with reference to the drawings which accompany and form a part of this specification.

General description This divisional application relates particularly to the consecutive counter associated with the check printer and the consecutive counter associated with the detail printer. The mechanism particularly involved is that associated with the resetting mechanism for these two consecutive counters, which is arranged so that both may be reset by the operation of a single lever. mechanisms are arranged to make the resetting particularly easy, by resetting one of the counters on the forward stroke of the resetting lever and the other counter on the return stroke of that lever.

Check printer-Consecutive counter It is considered desirable to consecutively num bar the checks issued from the machine and to carry out this result the illustrative machine is provided with a series of consecutive number printing wheels to which a unit is added during each operation of the machine.

The consecutive numbering counter is of the multiple pawl, deep notch transfer type, well known in the artand described in many patents, one of which is the patent to Carney, No. 876,295, dated January '7, 1908. The consecutive numbering wheels 60 (Fig. 2) are formed with printing characters and are loosely mounted upon the shaft 53.

The consecutive counter wheels are actuated in a manner well known in the art, by the ball 64 loosely mounted upon the shaft 53. The ball 64 has attached thereto a pin 65 cooperating with an arm 65 which is loosely mounted upon the shaft 32. The arm 66 at its rearward end is bifurcated to cooperate with an eccentrically mounted disk 61 securely attached to the driving shaft 3|. From the above it will be readily. understood that These for each operation of the machine, whether for a cash, paid out, or no sale transaction, the driving shaft 3I and cam disk 61 will make a complete revolution, thereby rocking arm 66 and bail 64 to add a unit to the consecutive counter of the check printer.

Detail printer-Consecutive counter The consecutive counter wheels I are similar in construction and purpose to the corresponding counter wheels 60 in the check printer. A bail I8I, pivoted to rock about the shaft I24, carries a pawl I82 (Fig. 3) for advancing the units wheel of the counter each time that the bail is rocked back and forth. Loosely mounted upon the shaft 32 is a bail I83 (Figs. 2 and 3) having at its left end two parallel rearwardly extending arms I84 which engage with the top and bottom respectively of a disk I85 mounted eccentrically upon the main driving shaft 3| and secured thereto. A link I86 connects the bail I83 with the bail I8i. During each operation of the machine, the main driving shaft 3| and the eccentric disk I35 make a complete rotation, thereby rocking the bail I83 first upwardly and then downwardly. By means of the link I86, the bail IBI and pawl I82 are rocked rearwardly and then forwardly to cause the pawl to engage a ratchet attached to the units wheel, whereby the consecutive counter is advanced one step.

Resetting the counters for the check printer and detail strip printer The resetting mechanisms for the consecutive counters in the check printer and detail strip printer respectively are shown best in Fig. 5. It will be remembered that the consecutive counter wheels I80 in the detail strip printer are rotatably mounted on a shaft I24, which shaft is adapted to be rotated by a segment gear N10 for resetting the consecutive counters. Similarly, the consecutive counter wheels Bil in the check printer are mounted on a shaft 53 which is adapted to be rotated in a clockwise direction (as viewed in Fig. 5) in order to restore the counter elements to zero. Secured to the shaft 53 is a spur gear 440 (Fig. 5) which meshes with a segment 44! pivoted to a side frame I2 at the right end of the machine. The resetting segments H10 and 441 are so connected by a series of levers and links that the two segments move at the same time, but in opposite directions. Normally, rotation of the segments is prevented by a locking plate 443 pivoted near its center to the end frame I2, the upper end of the locking plate engaging the lower end of the segment 448, thereby pre-- venting downward movement of the latter. Upward movement of the segment MI is limited by a pin 445 secured to the frame I2. The locking lever 443 is also provided with an arm 445 having detents 441 for engaging the pinions on the date setting wheels 30, whereby the date wheels are normally locked against rotation.

It is desirable that the resetting of the consecutive counters in both the detail strip printer and check printer be under the control of either the auditor or the store manager who is entrusted with a key for operating a lock M8 or M5. In the illustrative machine, an arrangement is provided whereby, when either the lock M5 or the lock 416 is turned, the aforesaid resetting mechanisms are unlocked for rotation. Referring to Fig. 1, a bell crank 449 is pivoted upon a stud 450 supported by the intermediate frame it. The upper end of the vertical arm 449 of the bell crank is slotted to receive a pin attached to the sliding bar 435. The forward end of the horizontal bar of the bell crank is similarly slotted to receive a pin on an arm 45I secured to a shaft 452 (Fig. 1). Shaft 452 is in direct alignment with shaft I1, as seen in this figure, and projects through the end frame I2. As seen in Fig. 5, the opposite end of the shaft 452 has secured thereto an arm 453, the free end of which is provided with a pin 454 riding in a symmetrical cam slot 455 provided in the locking lever 443. When the store manager inserts his key into the lock M5 and rotates the latter counter-clockwise, the shaft MI is shifted to the right and through a pivoted link connection (not shown) shifts the shaft 429 to the left. The latter rocks the bell crank 432 counter-clockwise, thereby moving the slidable bar 435 rearwardly. The bell crank 449, which is connected to the slidable bar 435 and the arm 45I on the shaft 452, causes this shaft to rotate counter-clockwise, as viewed in Fig. 5. The shape of the slot 455 in the locking lever 443 is such that whenever the shaft 452 and the arm 453 rotate in either direction away from the normal position, the locking lever 443 is rocked counterclockwise to its unlocking position. The rocking of locking lever 443 removes the upper end of the lever out of the path of the resetting segment 44! and simultaneously withdraws the detents 441 from the pinions attached to the date setting wheels 80, thereby unlocking the resetting mechanism common to the check printing counter and detail strip printing counter, and unlocking the date wheels in the check printer. When the auditor turns his key in the lock M6, the shaft MI is shifted to the left and the shaft 452 is rocked clockwise, as viewed in Fig. 5, thereby rocking the arm 453 upwardly; but the locking lever 443 is rocked counter-clockwise just as in the case when the managers key is turned.

The resetting segments H10 and MI are operated by a resetting lever 451 which is pivoted at 458 to the end frame I2 and which has a forward end projecting through a slot formed in the cabinet I9. Cooperating with the resetting lever 451 is a segment 460 pivoted on the frame I2 and slotted to receive a pin 46I on the resetting lever. The segment 460 is provided with teeth 463 engaging a pinion 464 secured to a shaft 465 loosely supported by the end frame I2. Also secured to the shaft 465 is an arm 465 which is connected by a link 461 to the free end of the resetting segment H10. The resetting segment N10 is pivotally mounted on a stud 468 which is supported by the frame H0.

The operation of the resetting mechanism for the consecutive counters of the check printer and detail strip printer is as follows:

Assuming that the locking lever 443 (Fig. 5) has been rocked counter-clockwise by the operation of either the managers or the auditors key, the resetting lever 451 will be free for operation. When the lever 451 is lifted, the segment 455 is rocked counter-clockwise and, by virtue of the link 410, rocks the resetting segment MI in the same direction. During the upward movement of the resetting lever 451, the shaft 53 is rotated clockwise by the segment 44I thereby restoring to zero the consecutive counters 60 for the check printer. Referring to Fig. 4, the shaft 53 is provided with a series of notches 41 i, each of which is in alignment with a springpressed pawl 412 pivoted on its associated counter element 50. When the shaft 53 is rotated clockwise, the notches 41I pick up the pawls 412, there-
